Tier 1 donation means tier 1 access to my content and that's it

Tier 2 donation is basically Tier 2 access as the sole perk

Tier 1 access means you get access after Tier's 2 and 3

Tier 3 donation means access wise you are unrestricted, but ultimately that's all you get aside from thanks at the end of chapters. You don't get voting rights, you don't get character commissions.

Tier 2 access means you get to access a week after Tier 3 and six days before Tier 1

Tier 3 access is basically unrestricted and you get to commission a character for any active story

Unrestricted access to my stuff and premium voting rights, character commissions only available if upgrading from previous tier

Ultimate tier, everything on offer. You get access to my content, Divine voting rights, and provided you updated from Gold you get two Character commissions.
